INHALER.

.SPECIFICATION forming part of Letters Patent No. 688,864, dated December 17, 1901.

Application illed April 6, 1901. Serial No. 54,684. (No model To @ZZ whom, it' may concern:

Be it known that I, SOLOMON MATHEW KEMP, a citizen of the United States, residing at the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Inhalers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appe rtains ro to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the class of surgical appliances which are known as inhalersg and the object of the invention is the production of an efficient combination vaporizer and inhaler by the use of which medicine in the form of vapor free 2o from moisture is forcibly directed against the affected part.

The nature of the invention will be readily comprehended, reference being had to the following detailed description and to the ac- 2 5 company-ing drawings, in which- Figure l is an elevation of a combined vaporizer and inhaler embodying the invention. Fig. 2 is a vertical central sectional View. Fig. 3 is a sectional view on line 3 3 of Fig. 2.

Referring to the drawings by letter, A denotes a vessel which receives the medicine. 'The body of the vessel is supported by a hollow base t, which allows of a lamp :t being placed beneath the body to effect by heat the vaporization of the contents, or, if preferred,

the vessel may rest on a stove and receive radiated heat. The upper part of the vessel is preferably contracted, as shown, and is internally screw-threaded to receive the screw- 4o threaded portion of acap which forms a removable closure. A gasket d is interposed between the vessel and cap to secure a tight joint. Through the cap are passed two tubes,

one of which, E, terminates near the bottom 45 of the receptacle or vessel, and its upper end is connected by a flexible tube f with a compressed-air supplier,wliich may be the bulb f shown. In the tube E is a chamber e, preferably of spherical form, and centrally or 5o thereabout of the chamber is a disk e', im-

perforate at its central portion, but having beyond said portion a circular series of perforations e2 c2. The upper portion of the tube E extends within the chamber to a point closely adjacent to the center of the disk to restrict its opening,and the lower portion terminates at its junction with the chamber.

The tube G is constructed similarly to the tube E, with the difference that its lowerend terminates above the liquid-level in the Vessel. is a disk g@ having perforations g2 g2. To the upper end of the tube G is connected a iiexible tube 7t,which carries a suitable throatpiece or nose piece or pieces.

In practicing the invention the medicineis introduced into the receptacle or vessel, and heat being applied the medicine is converted into medicated vapor. Compressed air is now supplied-,for instance,by repeatedly compressing the bulb, and as the air enters the vessel through the tube E the vapor is displaced and expelled from the vessel and passing through the tube G is finally discharged through the throat-piece or nose piece or pieces. The compressed air before entering the vessel is compelled to pass through the perforations in the disk. After leaving the vessel the vapor enters the chamber g, and by reason of the imperforate central portion of the disk it is compelled t'o move laterally before it can escape through the perforations g2. From the perforations the vapor passes to the comparatively restricted opening of the upper portion of the tube G, after which itis discharged from the tube h. The circuitous passage provided for the discharging vapor results in the retention within the Vessel of moisture derived from unvaporized liquid and condensation, the moisture which is in suspension collecting on the under side of the impert'orate portion of the disk and falling therefrom back into the vessel through the lower portion of the tube'G. The vapor discharged from the appliance is therefore largely deprived of moisture and its efficacy consequently greatly increased. The disk is preferably of concave form in cross-section.

I claim as my invention- An inhaler comprising a vessel in which medicine is vaporized by the action of heat, a coinpressed-fluidinlet tube leading into the 6c In said tube G is a chambery, in which IOO In testimony whereof I affix my signature in presence of two Witnesses.
